How to turn off the thumbnail preview?

ImageConverter Plus has the option to allow for conversions with a right click and the ability to show a preview with the right click. Depending on the font size of your display, your screen display size and other software you have installed - you may not find that preview helpful (which is what it sounds like in your case).

To turn off the thumbnail preview please modify the lines:

from

[Shell]  

ThmbEnable=1  

to  

[Shell]  

ThmbEnable=0

into the file: icp.ini in the ImageConverter Plus installation folder which is typically \Program Files\ImageConverter Plus
